Yoga Sutra 3.33 by supernormal knowledge he knows everything

The supernormal knowledge called prātibha helps the yogin across, it being the first phase of knowledge-born-of-discrimination – like the glow of the sun at dawn. From this too the yogin-s know everything, namely from the rise of the supernormal knowledge called prātibha.

By the prātibha supernormal knowledge too (he knows) everything. When the yogin makes saṃyama on the self (ātman), or is supremely devoted to the Lord (īśvara), the knowledge which rises spontaneously in his mind is supernormal and helps him across, it being the first phase of knowledge-born-of-discrimination which is going to be described.

like the glow of the sun at dawn: becoming to some extent visible at daybreak as the reddening, when it is about to rise. This is the first phase. From this too the yogin-s know everything, namely from the rise of the supernormal knowledge of prātibha.
